Abstract
A switch that facilitates remote port mirroring is described. The switch can include an encapsulation mechanism and a forwarding mechanism. The encapsulation mechanism can be configured to encapsulate a copy of a first packet in a second packet, thereby preserving header information (e.g., a VLAN identifier and/or a TRILL header) of the first packet. The forwarding mechanism can be configured to forward the first packet using header information of the first packet, and forward the second packet using header information of the second packet. The second packet can be received at a destination switch which extracts the first packet from the second packet, and sends the first packet on a port which is coupled to a network analyzer.
